Infant died with marijuana in his system and crushed skull last April. His mom and her boyfriend now accused of murder.

A mother and her boyfriend in Alabama are accused of murdering her 15-month-old son after an autopsy showed the baby had marijuana in his system and died from blunt force trauma to the head, authorities said.

Last April, the infant, Emery Michael-Knox Wilson, was having trouble breathing, and he was rushed to an area hospital in Lawrence County and then transferred to a medical facility in Birminghan, where he died.

At the time, the baby’s mother, Jordan Ellan Harmon, 27, was arrested and charged with child abuse. On Sept. 17, she was released on $60,000 bond, according to WAFF.

“He had a broken arm but it started to heal back. He had a crushed skull and numerous abrasions," Lawrence County Sheriff Max Sanders said of the baby’s condition, WHNT reported.

Nearly 10 months later, the sheriff’s office received autopsy and toxicology results related to the death. “The child died from blunt force trauma to the head,” Sheriff Sanders said, explaining the child had abrasions and lacerations to the scalp as well as marijuana in his system.

“It’s a 15-month-old child [who] can’t help [himself],” Sanders noted.

On Jan. 26, investigators questioned Harmon about the autopsy and toxicology report results. A day earlier, her boyfriend, Travius Sebastion Coleman, 28, was also questioned.

Both Harmon and Coleman were arrested and each booked into the Lawrence County jail on charges of aggravated child abuse, chemical endangerment of a child, and murder

According to WAFF, Harmon has three other children who are in the care of family.
